  • Berman, Sonia (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    An automated database design tool called ADD has been developed at the University of Cape Town. This system obtains a requirements specification from a user and from this generates a relation scheme and a Codasyl schema. ...
  • Mann, R.J. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    A basic description of the facilities of the computer modelling package, AUTO-CONFIGURATER, is presented together with detailed procedures to calculate the required input parameters from monitor statistics. Techniques to ...
  • Currin, Desmond C. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    Generalized network problems involve the optimization of a flow through a network. In contrast to normal networks, generalized networks include multipliers which alter the flow as it passes through the arcs. This enables ...
  • Cuthbertson, A.J.; Van Niekerk, I.J.; Turton, Trevor (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    This paper describes the research that was undertaken in designing a disk space management system. The system has strong similarities to the management of real storage in a virtual storage environment. These similarities ...
  • Bruwer, P.J.S. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    Performance evaluation techniques can contribute substantially to the successful management of the information services function in an organization. Unfortunately the design and implementation of computer-based ...
  • Schach, Stephen R. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    Details are given of an implementation of Grimbleby's algorithm for the common spanning tree problem with running times up to 50% less than for the original implementation. An explanation is given as to why implementations ...
  • Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    The need for modelling techniques to allow blocking of tasks prior to admission to the computer system in queueing network models is described. A detailed algorithm which presents a technique to enforce blocking by priority ...
  • Van Rooyen, H.O.; Weiermans, D.J. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    Nebula modell_ing is_ a generalised structural modelling technique which applies to any finite set of objects (entities) and n-ary relat1onsh1ps (n ~2). A nebula model can be presented in either diagrammatic or tabular ...
